Report no. 87638 dated 20 September 2016 from the SSEF Swiss Gemmological Institute stating that the rubies are of Burma (Myanmar) origin, with no indications of heating and the colour of part of these rubies may also be called 'pigeon blood red' in the trade; also accompanied by an appendix stating that the rubies possesses extraordinary characteristics and merits special mention and appreciation. These rubies have been carefully selected for this necklace to beautifully match in quality and saturated colour. The small inclusions found by microscopic inspection and the analysed properties of these rubies are the hallmarks of rubies from the well-reputed mines in the Mogok valley and -for few of them-from Mong Hsu (southeast of Mogok). Their attractive and beautifully saturated colour, poetically referred to as 'pigeon blood red' for part of these rubies is due to a combination of well-balanced trace elements, which are characteristic for the finest rubies from Burma (Myanmar). Assembling a matching selection of natural rubies from Burma of this quality is rare and exceptional.

The total weight of the certified rubies is 57.72 carats.
